Dust collector fan, dust collector base station and cleaning equipment

The invention relates to the technical field of cleaning equipment, and provides a dust collector fan, a dust collector base station and cleaning equipment. Wherein the dust collector fan is provided with a fan outer shell, a fan inner shell and a fan body; the fan inner shell is located in the fan outer shell, the fan body is installed at the first end of the fan inner shell, the first end of the fan outer shell is connected with the first end of the fan inner shell, and the first end of the fan outer shell is closed; the air vent is formed in the side wall of the fan inner shell, the air outlet is formed in the second end of the fan outer shell, air enters the position between the fan inner shell and the fan outer shell through the air vent and then is exhausted through the air outlet, the flow speed of the air is gradually reduced in the process, and therefore noise generated when the dust collector fan is used is reduced. According to the dust collector base station, a dust collector fan is communicated w
